What an interesting find. Thank you 'dcrfan' for the posting. The lower picture of the Bedford truck with trailer has the identity of CFMU 2 on the door. As our Maps Page illustrates, this unit was originally formed in Chatham during May 1944. After D day, as the European War progressed , it spent some time in Copenhagen finally ending up in Wilhemshaven. At one time, this particular unit had Lt Cdr Bradford, of 55th 'Dog Boat' Flotilla fame, as its CO.

There is still much to know of these valuable units; many were formed in the Mediterranean and Far East. Further information and any images of these and their working would be most welcome.

I've been busy ready books on coastal forces to try and better understand the maintenance units expecially in the Med.

In Flag 4 by Dubley Pope (pgs 109-110) he explains Lt Cdr Allan scrounged equipment off the Americans and 'spent several days after the German surrender in Tunisia combing the Cape Bon battlefields to see what vehicles and equpiment the Germans left behind'.

In Dog Boats at War is this picture presumably taken at Bastia. I believe N.O.I.C. on the truck doorwould be Naval Officer in Charge:

It shows an a US Allis-Chalmers tractor with a mounted crane and a British Albion truck which I assume would have a machinery body as they were common this chassis. The nose of a third vehicle on the right was a bit more difficult to identify but I now have it. It is a German Auto Union Horch so presumably one of the vehicles recovered in Tunisa. The picture below shows a typical Horch.

I do like your detective work – the identifying of the Horche truck - well done. The Med CF mobile units certainly do need further research. Our Mediterranean Map page give a very brief outine but still has many gaps. The importance of Naval Parties (NP’s) in the initial stages of CFMU set ups has not really been fully explained nor completely understood. NP 645 for example, eventually to become HMS Hamilcar, was in situ as a forward maintenance unit at Bizerte (identified as ‘Harwood Port Party) as was NP 623.
LtCdr Ben Harlow’s listings on the Naval-History.net website wets the appetite for further research.
